tg 06c6be0a70 shave off another 468 bytes: we’re 300 bytes smaller than BEFORE the
cat builtin was added now… (also removed utf-8 from source files, in
favour of just ASCII)
2010-08-28 20:22:24 +00:00
tg 3747722db4 improve string pooling: saves 316 bytes in .text 2010-08-28 18:50:58 +00:00
tg c187f3089f a tad annoying, when external programmes such as GNU screen are running,
we don’t get SIGWINCH when the window size changes during the runtime of
that, so, the signal is only usable reliably during editing in the shell
and we re-check the window size before each interactive edit line again

tg c11d35312a Michal Hlavinka from Red Hat found another SIGSEGV
fix: when iterating over all Sources, know when to stop…
2010-07-21 11:31:16 +00:00
tg 7c91e018f4 • merge printf from OpenBSD
• deactivate %a and %A since our libc doesn’t have it
• rewrite the mksh integration code to use shf instead of stdio, removing
  floating point support always in the process, as shf doesn’t support it
  ⇒ saves 11114 (6706 text, 168 data, 4240 bss) with dietlibc on Debian
• fix -Wall -Wextra -Wformat -Wstrict-aliasing=2 for gcc (Debian 4.4.4-7)
• fix these and -Wc++-compat for gcc version 4.6.0 20100711 (experimental)
  [trunk revision 162057] (Debian 20100711-1) except:
  – a few enum warnings that relate to eglibc’s {g,s}etrlimit() functions
    taking an enum instead of an int because they’re too stupid to adhere
    to POSIX interfaces they design by themselves
  – all “request for implicit conversion” involving a "void *" on one side
• tweak the manual page somewhat more

tg ff9f89f22f Fix two more POSIX conformance bugs and minor documentation/comment issues 2010-04-08 13:21:08 +00:00
tg 2557cfbbe5 move label, see <Pine.BSM.4.64L.1003311156380.24549@herc.mirbsd.org> (my
first paragraph in that) for reason: to make it more clear from the code

tg 5beee95d6b at least _parse_ the construct ${foo+(bar)} correctly
(whether the output is correct is still up for debate)

tg c67bed8790 • unbreak testsuite for MKSH_SMALL
• sync version and © year
2010-01-28 20:58:34 +00:00
tg 4aba1d69b5 DEC ucode cc politely reminds me this is not a good way of doing stuff, 10x 2010-01-28 20:52:08 +00:00
tg 2765a07564 when using persistent history (and not MKSH_SMALL), let the shells
concurrently accessing the same $HISTFILE be more synchronised with
each other: empty lines (just pressing Return) and duplicates (that
are split and written twice by the lines loaded from $HISTFILE in
the meantime); requested by Maximilian “mxey” Gaß in #!/bin/mksh
2010-01-25 16:12:57 +00:00
tg 703551bd4f attempt a better fix: break off widthadj upon encountering NUL,
add remaining columns as octets (should also speed optimise)
2009-12-05 20:17:59 +00:00
tg 86d4dee0da valgrind (thanks ciruZ for trying) found uninitialised memory use
in utf_skipcols by x_goto
2009-12-05 19:44:09 +00:00
tg 2094e3f25c since we have wcwidth anyway, expose it as ${%strvar} to the user, iff
utf8-mode is enabled (otherwise it'll be a synonym for ${#strvar} aka
the number of octets in it)
2009-11-21 23:23:20 +00:00
tg 5f58261287 fix long-standing parenthesēs problem: ((foo) || bar) is now parsed corr. 2009-10-04 12:45:23 +00:00
tg c2e5737fca fix dollar quotes in here strings and here documents (regression) 2009-10-04 12:44:19 +00:00
tg 33b9f8b666 * rename "set -o posix" (FPOSIX) to "set -o sh" (FSH) because it's not
just a "somewhat more POSIX" but also a "/bin/sh legacy kludge" mode
* consistently capitalise POSIX and SUSv3/SUSv4 (same as AT&T ksh) and
  Bourne shell
2009-10-02 18:08:37 +00:00
tg 1dfb13b603 change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come:
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
2009-09-24 17:15:33 +00:00
tg 1a28786229 * shrink MKSH_SMALL even further by removing functionality like
some GNU bash extensions (suggested by cnuke@) and bind macros
* make the random cache more efficient (and the code potentially
  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed
  (i.e. state has changed or user has set $RANDOM, but not onfork)

tg 9fd4b9db41 $'…' functionality, documentation improvements, fixes for backslash
expansion in all modes, regression tests for both kinds of backslash
expansion; unbksl() revamp; make CTRL macro available globally
2009-09-19 21:54:46 +00:00
tg 4392aced96 the capability to get array indicēs (keys), Korn shell style
bash4 doesn’t have it at all, despite knowing associative arrays
zsh does it………… differently and weird

this is for indexed arrays, as mksh doesn’t have associative arrays
but it should help ☺
2009-08-28 22:39:09 +00:00
tg 4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry
① also saves time during texpand :D

XXX this doesn’t work well with the current indexed-array implementation
2009-08-28 20:30:59 +00:00
tg 7240c843ce this is a rather stupid diff: give ktsearch/ktenter the capability to
return information needed to do a real ktremove instead of the pseudo
ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries
are still counted)
2009-08-28 19:57:43 +00:00
tg ca1f967a45 • use Jenkins’ one-at-a-time hash for mksh keytabs, as it has
much better avalanche and no known funnels
• improve comments
• fix some types (uint32_t for hash, size_t for sizes)
• optimise ktsort()

no functional change, I think
2009-08-28 18:54:01 +00:00

tg 0432f97ffe more KNF, mostly whitespace, this time more manual labour applying style(9) 2009-06-10 18:12:51 +00:00
tg 6b2ad96bac some rather mechanical KNF, now that style(9) clarified on the status
of sizeof() as a function-like unary operator; use parenthesēs around
sizeof and return args consistently too
2009-06-08 20:06:50 +00:00
tg da5dc48cd0 implement an extension that an interactive mode input line, when
starting with an ‘!’ exclamation mark at the beginning of a com-
mand (PS1 not PS2), shall have the same effect as the predefined
“r” alias, to be compatible with csh and GNU bash’s “!string” to
«Execute last used command starting with string» – documentation
and feature request provided by wbx@ (Waldemar Brodkorb)

• histrap.c, lex.c, misc.c: get average stack frame size to <= 768 bytes

tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh
  to get correct copyright years per-file, as is BSD custom

tg 31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some
  things I learned will probably improve things more but make me use the
  original form as base (especially for space savings)
* let sizeofN die though, remove even more casts
* optimise, polish
* regen Makefiles
* sprinkle a few /* CONSTCOND */ while here

tg 042086e49e rename utf8-hack to utf8-mode (use set -U or set +U instead, anyway)
and announce less hackish things
2008-12-04 18:11:08 +00:00
tg 4897682502 Alias expansion has a recursion check which tries to break the cycle if
encountered. However, when reading end of input, the source type is set
to SEOF while popping, whereas the recursion check code only checks for
an SALIAS type.

Fix: add a new SF_HASALIAS flag; change u.tblp from being valid if type
is SALIAS to being valid if SF_HASALIAS is set; set SF_HASALIAS for the
created SALIAS sources; set SF_HASALIAS and u.tblp when creating SALIAS
whose next is SEOF on the SEOF source as well.
